MONOLITHIC, METALLIC REENFORCED SLAB Filed Jan. 23, 1932 2 Sheets-Sheet2 Patented June 30, 1936 unirse stares PATENT OFFICE IVIJNMTMC,METALLIC-REENFRCED SLAB v: ,5; V nn Application .sanitary lviy inventionrelates to veneers application the external walls of buildings.Primarily, l' concerned with a veneer which :nay be quiclily applied toa Wall, and, upon suon application, will lend to the Wall an appearanceof masonry. Broadly, this concept has for years been in the minds ofthose skilled in the art, but to my knowledge there has been no veneerstructure embodying the particularly effective characteristics of myinvention.

While the novelty of combination in the appended claims may be ofspeciic nature, it is nevertheless of great' practical value. lvlystructure comprises a monolithic, metallic-reenforced slab which hasincorporated in its body plaques resembling in elevation the members oithe inasonry which in service the veneer is to reproduce. It will beobserved that an important' characteristic of my veneering slab lies inthe fact that it includes a plurality-or" preformed, burnt briquettes(plaque members) spaced apart and arranged in predetermined pattern; thebody material of the slab extends into the intervals between thebriquettes, so that when installed upon a Wall, the Wall -taires on theattractive appearance of laid bricl; masonry-practically no pointing orlling in of the slabs being necessary after installation. In brief, itis only necessary to apply my slabs to a Wall, and, Without furtherlabor, the Wall is attractively nished.

Figs. li, m and lV are fragmentary views in cross section, to largerscale and taken respectively on the planes H E, mmm, and V-W of Fig.

Figs. 'Vm to Xl inclusive illustrate still other modications; and,

Figs. XH and m show a mold fragmentarily, and illustrate how the veneerslabs may be constructed.

The veneer structure of my invention comprises a plurality of briquettesl; the briquettes may be vof desired shape and color, and in thiscase,the briquettes are preformed of clay and burnt in kilns, as standardbricks are made. The briquettes are relatively thin, so that the expanseof brioi lr'ennsyivania 23, i932, lilo. 588,323

ailettes is of slight thicln'less, conservation ci terial andminimization of Weight desi ata. The expanse of briduettes is supportedon one face in a monolithic slab 2 of cementitious material, which inthis case is a rich, line concrete. Within its body, extending in thegeneral plane of its expanse, is a metallic reeniorcernent 3.Light-Weight metal lath or other Well-known perforaternetal sheets mayserve as the reeniorcement. At various points throughout the slabstructure holes l are provided for attaching screws or nails. Fig. Villustrates how a nail 5 may be driven through each hole d into thebacking Wall l which is to be faced with the veneer. The nail holes liebetween the briquettes and are countersunk, as indicated-thus mortar 'lcan be spotted over the nail head.

lt is of importance to note that the body of the slab 2 extends into theintervals and provides iillets between the briquettes. All or a portionof the cementitious material forming body of the slab may be coloredwhen in the green state, so that in assembly and in completed state thecody o1" the slab 2, by extending into and appearing Within theintervals between the briquettes, lends to the Whole, in side elevation,the pleasing appearance of nicely pointed briclr masonry. in deed, thestructure practically avoids the necessity of pointing which isnecessary in all practical slab veneers in use today.

In case the slabs are terminated at their edges intermediate theintervals between alternate briquettes (ci. Fig. I), it Will benecessary to ill in and point the regions 8 between adjacent slabs, andin the alternate horizontal rows oi 'the briquettes, the side edges ofthe structure include half briquettes la, which upon assembly of theslabs meet in pencil line seams il. Even this slight pointing operationis eliminated by constructing the edges of the slabs as indicated inFigs. VI and V'D. That is, the right-hand edge fio 0i' the slab Acarries thefwhole fillet i@ for the briquettes of the adjoining edges ofthe two slabs A and B. The co-operating half-briquettes la are, ofcourse, of unequal dimensions, but the structure is, manifestly, onereadily to be constructed and installed` Figs. VIII and IX show stillanother edge construction for the slabs; itis this: Instead of includinghalf-briquettes la in the alternate horlzontal rows of briquettes, Iform in the monolithic bodies 2 of the slabs recesses il, such that whenthe veneer slabs are assembled the several recesses li become paired inregistry, providing a pocket for the subsequent insertion of briquettes(ci. Fig. 1X). 'I'he briquettes l2 are "butterecij with mortar on theirrear faces and inserted in the packets (i I-l l) thus provided.Accordingly, the iinished application of veneer, even upon closeobservation has a uniform reguiar and pleasing appearance.

Figs. X and XE illustrate in cross section how ,the briquettes (Ib andle) may be various-ay fashioned to decrease their weightand conserve theceramic material of which they are formed. Additionally, the bondingbetweenthe body 2 and briquettes may be in this manner increased.

-The construction of my veneer may advantageously be eected in a moldi3, in whose bottom a plurality of shallow pockets I4 is provided, sodisposed with respect to one another as the briquettes are desired to'ne in the finished product. The briquettes are placed in the pockets.the pockets being of less depth than the briquettes. Next, lthecementitious material, suitably prepared with the desired coloring isspread over the briquettes withinthe mold, see Fig. XII, and theintervals between the briquettes are provided with molded ilets which,due to the structure of the mold terminate inwardly of the faces of thebriquettes that are exposed in the finished structure. That is. themetallic reen= forced monolithic slab is applied to the one face of theexpanse of briquettes, and said slab in cludes in its strelcture moldedilllets which extend into the intervals between the briquettes andterminate inwardly of the opposite faces of said expanse. Conveniently,the initial application of material may terminate flush with or slightlyabove the top faces of' the briqnett'es in the mold, Then the metalreenibrcement 3 (Fig.

aosaeia d XIII) islaid in position, and the remainder of the mold lled,on top of the reenforcement, with a cement mix of less expensive nature.I contemplate that the last application of cementitious material may bein the form of uncolored 5 grout, but, of course. a slab 2 builtcompletely of the colored material lies within the invention., Asindicated in'dotted lines, pegs or pins I5 may be positioned in themold, either before or after 'casting the slab, to provide the nailholes 4 al#- 10 luded to above. I claim as myinvention:

A panel for finishing the external walls'of a building comprising a.thin monolithic body o! solidied mortar including in the plane of its l5cxpansea cancellate sheet of metallic reenforcement, a plurality of thinbricks of red clay embedded in said mortar, said red bricks being in theexpanse of said monolithic body arranged in staggered relation in thesame general manner that the bricks or blocks of ordinary masonry arestaggered in side elevation, said thin bricks being spaced apart in thegeneral plane of their expanse, brick pointed molded iillets cast andhardened in the spacing between said bricks and in monolithicintegration with said body to constitute said panel a thin pointed brickunit, the edge of said panel being provided with recesses of a depthequal to the depth of the pointed and nished fillets cast between thebricks and'being 30 adapted in assembly for registering with thecomplementary recesses oi' adjoining panels to provide together pocketsfor the reception of whole bricks to overlie the lines of abutment oithe panels.
